Any ionic compound in which the force of attraction between the oppositely charged ions is weaker than the force of attraction that water molecules exert on each ion, dissolves in water. Water is known as the universal s... More »

Since non-polar substances are held together by weak van der Waals interactions and water molecules use strong hydrogen bonds, the van der Waal interactions of non-polar substances are not strong enough to break the hydr... More »

Sugar dissolves in water because both substances are polar substances. Water dissolves the majority of substances that are polar or ionic. The fact that sugar dissolves in water is unusual because most molecular compound... More »

Ammonium nitrate dissolves in water with an endothermic reaction, a chemical reaction that consumes heat rather than releasing it. The temperature of the solution is lower than the starting temperature of either componen... More »

How fast candy dissolves in water depends on how much candy is used, the temperature of the water, the composition of the candy and its surface area. The duration can range from minutes to hours or even longer. Candy is ... More »

An equal amount of salt in hot and cold water dissolves at about the same speed. However, the same amount of sugar added into hot and cold water dissolves faster in the hot water than in the cold water. More »

Coffee dissolves in water, but the extent of coffee solubility varies. Ground coffee beans do not completely dissolve in hot water, while instant coffee, otherwise called soluble coffee, does. More »
